SLAB OR PLATE.

SPECIFICATION forming part of Letters Patent No. 741,043, dated October 13, 1903- Application filed December 22, 1902. Serial No. 136.107. (N0 model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM L. KANN, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Improvement in Slabs or Plates, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a rear perspective view showing a portion of a side wall provided with my improved slabs, showing the securing means.

Figs. 2 and 3 are enlarged detail views showing two difierent forms of the holding-bridges or cross-bars. Fig. t is a top perspective View of a slab or plate arranged for a ceiling. Fig. 5 is an enlarged detail of the anchor and bridge in this form. Fig. 6 is a detail view showing the manner of securing the slabs or plates to a floor beam or support to form a ceiling, and Figs. 7 and 8 are detail views showing anchors which may be used for supporting-the slabs as shelves in a show-case.

My invention relates to slabs or plates, especially those of glassy or ceramic nature, and is designed to provide improved means for holding or supporting such slabs in posi tion, such as in a wall or ceiling or suspended as a shelf.

The invention consists in providing an an-' chor having ahooked or bentportion extending under a bridge formed in the rear part of the slab, and, further, in the construction and arrangement of the parts, as hereinafter with edge recesses 5 througha narrow neck or hole beneath the connecting-bridge 6 of the slab material. r

The anchors 7, which I have shown as in the form of metallic wires, are provided with bent or hooked inner ends 8, which are slipped into the rear recesses and under the bridges. The wire is then held by plasterof-paris or a hardening compound which is filled into the recesses. In Fig. 2 Ishow an enlarged detail view of the anchor and bridge, the anchor having its outer end portion 9 bent and embedded in the plaster 10 of the wall. This wire may be" secured to a nail or twisted about any projection to hold the slab in position. At the lower edge of the slab 2 I show a slightly-different form of recess, the bridge 6 having a groove 11, through which the wire may extend between this slab and one of the narrow slabs 3. The securing wires 7 of the narrow slab 3 are arranged similarly to that of Fig. 3, lying together between the meeting edges at the ends of these slabs.

In using the slabs or plates for covering ceilings I preferably form them as shown in Figs. 4 and 5. In this form the bridge portions 6 are formed between two similar recesses 4 which deepen toward each other until they connect through a hole beneath thelbridge, as shown in Fig. 5. In this case the anchor takes the form of a loop 7, having its legs bent under the bridge on opposite sides and secured by the plastic hardened material. Where the ends of these tiles meet underneath beams or connectorsin the ceiling, I

preferably form the rear and end recesses as shown in Fig. 6, the wire loop 7 extending through both recesses,one in the edge of one slab and the other in the edge of the adjacent slab, the legs of the wire being passed through a hole in the web of the floor-beam 12 and twisted together, as shown. In this case the wires are embedded in plaster-ofparis or similar material, as before.

In Figs. 7 and 8 I show the slabs arranged for supporting shelves or for similar purposes. In this case the recess L extends downwardly and thence under a bridge portion 6, but doesnot connect with another recess on the opposite side of the bridge. In this case, again,'the anchor 7 has a bent inner end extending under the bridge,while its outerend may have a button 13, as shown in Fig. 7, a hook 14, as shown in Fig.8, or other suitable shape for receiving the supporting cord or chain.

The advantages of my invention result from the use of the separate anchor which is secured in the hole or recess in the back of the slab and has a portion extending beneath a bridge portion of the slab. The anchor is thus firmly secured, while at the same time it is not afiected by expansion and contraction, as in the case of integral projections on the slab, and will serve to hold the slab securely in place.

Many changes may be made in the form and size of the slabs or plates, the shape of the recesses and bridges, the material of the slab and the anchor, 850., without departing from my invention.

I claim- 1. A slab or plate having a recess extending under a bridge portion, and an anchor having a hooked or bent portion in the recess; substantially as described.

2. A slab or plate having a rear recess ex- W. L. KANN.
